The present invention relates to a cleaning apparatus capable of washing a metal container with a hydroxyl radical.

Conventionally, as a thermos flask or a table-type thermos pot for a metal container made of a metal such as coffee or tea, the opening portion is narrow and the inside thereof is not easily cleaned. Therefore, there is a market for selling the shape of the container. Sponge, however, every time you need to clean the thermos, it needs to be cleaned by a special sponge, which is very annoying to the user. Therefore, if you use water or a neutral detergent and only rinse the inside of the container, If it is washed repeatedly, it will not be able to remove the dirt of the coffee or tea stains attached to the inner surface of the container and cause the inner surface of the container to gradually fade. Thus, if it is faded, it is not easy to remove the dirt with a sponge. In this case, Next, the inside of the container must be cleaned by a detergent such as a solubilized oxygen-based bleaching agent. However, the oxygen-based bleaching agent must be immersed in the cleaning liquid for several hours to ten hours before the cleaning bottle can not be cleaned immediately. It is clean and can't even meet the needs of users.

Under such circumstances, it is known to apply a positive voltage to an aqueous hydrogen peroxide solution, and apply a negative voltage to a hydroxyl radical generated by the object to be washed, thereby decomposing the attached object to be washed. For example, JP-A-2002-173799 and JP-A-2011-56422 are referred to as Patent Documents 1 and 2, respectively.
